Fingerprint is the fingerprint identification method, which uses the texture and fingerprints of the front and the thumb to identify the identity. Fingerprints are a reliable way to identify identities, because each person's texture on each finger is different and does not change due to development or age. Fingerprinting is used to reveal a person’s true identity, although I personally denied that the use of a pseudonym or appearance changes due to age illness, orthopedic surgery, or an accident. The use of fingerprints as a means of identifying identities is known as fingerprint identification and is an indispensable aid in modern law enforcement.
The entire length of each stripe of the epidermis is covered with sweat gland pores and is fixed on the dermis by two rows of nail-like protrusions or nipple-like protrusions. Some wounds such as burns, abrasions, or cuts on the epidermis do not affect the structure of the striae or change the nipple-like nipples on the dermis. The original texture is reproduced on any newly growing skin. However, any trauma that destroys the nipple-like protrusions on the dermis will permanently erase the fingerprints.
Any textured area of the hand or foot can be used to identify the identity. Fingerprinting, however, is superior to other parts of the body because fingerprinting takes the least amount of time and effort, and the type of fingerprint (conspicuous outline or shape) is easy to classify and facilitate archiving.
Although the technology of fingerprinting and its use in the system originated in the United Kingdom, the place that played a great role was in the United States. In 1924, two large fingerprint databases in the United States were merged into the core of the archives currently held by the FBI’s identification office. . By the end of the 20th century, there were more than 90 million fingerprints stored in this office. Fingerprint files and retrieval technologies have been computerized, making it much faster to compare and identify specific fingerprints than before.
Other "fingerprinting" techniques have also been developed. These techniques include the use of sound spectrographs—a device that graphically depicts sound variables (such as frequency, duration, and intensity)—taking sound images or sound waves, and using a technique called DNA fingerprinting. It is a method of analyzing each person's DNA in different ways to identify material evidence (blood, semen, hair, etc.) belonging to a suspect. The latter assay has been used in parental identification tests and forensics.
